  20. Gypsy Moth Life Cycle Eggs/Egg Mass; 200 to 800 eggs in a egg mass Hatch: early May, timed with oak leaf-out Located on tree trunks, under branches Caterpillar: ID: 5 pairs of blue dots & 6 pair of red dots 6 to 8 weeks, to end of June-early July 5 to 6 stages, larva instars Shed skin at each instar Most of the leaves eaten in last two instars Prefer oak, aspen, basswood, beech Pupa/Cocoon: Caterpillar to moth 1 ½ to 2 weeks Reddish to black color Moth/Adult: Male & female moths last for 1 to 2 weeks Mate, lay eggs, & die Eggs over-winter until following spring Female white and male buff colored Female moth does not fly

  21. Hemlock Wooly Adelgid (HWA) • Non-native – native to China and Japan • First found in PA, in the late 1960s • Now has been ID’ed in 2/3 of PA Counties • Population has been very low for several years • Feeds on all hemlock varieties • A very complicated life cycle • Two generations per year but 2nd generation is inactive during the summer • Feeds by attaching itself to the base of the needle and sucking sap • Others – elongate scale, mites, drought Forecast • Increasing again in 2006 – mild winter

  22. Emerald Ash Borer Exotic Beetle from Asia Discovered in Michigan in July 2002 Discovered in western PA in June 2007 Adult Beetles: Metallic green wing covers – ½” to ¾” long Peak emergence – late June & early July Live for about 3 weeks – mate, lay eggs & die Feeds on the margins of ash leaves Males are smaller than females Adults are strong fliers – up to a mile Eggs/Egg Mass: Female can lay 60 to 90 eggs – July/August Eggs deposited in bark crevices anywhere on the tree Eggs hatch in 7 to 10 days - August Larvae/Borer: Bore into tree immediately after egg hatch White grub – full grown 1” to 1 ½” long Feeds on the cambium layer between the bark & wood Only feeds on ash species Feeding is completed in autumn Over-winters in phloem/cambium layer Pupation: Larva to adult beetle (pupation) occurs in April/May Damage to tree: Feeding in the phloem/cambium layer girdles the tree Feeds on the upper branches & main stem first Trees often die after 3 to 4 years after infestation

  23. Eastern Tent Caterpillar Life Cycle Eggs/Egg Mass; 100 to 250 eggs in mass Hatch: end of April/early May Located on ends of branches Caterpillar: 6 to 8 weeks, to end of June 5 stages, larva instars Shed skin at each instar Most of leaf eaten in last two instars Prefers cherry, apple, and other fruit trees Pupa/Cocoon: Caterpillar to moth 1 ½ to 2 weeks White to yellowish color Moth/Adult: Male & female for 1 to 2 weeks Mate, lay eggs, & die Eggs over-winter until following spring

  24. Forest Tent Caterpillar Life Cycle Eggs/Egg Mass; 100 to 250 eggs in mass Hatch: end of April/early May Located on ends of branches Caterpillar: 6 to 8 weeks, to end of June 5 stages, larva instars Shed skin at each instar Most of leaf eaten in last two instars Prefers sugar maple, ash, aspen Pupa/Cocoon: Caterpillar to moth 1 ½ to 2 weeks, Moth/Adult: Male & female for 1 to 2 weeks Mate, lay eggs, & die Eggs over-winter until following spring
